3. Save the new configuration files and images (such as sip.ld) on the boot
server.
4. Reboot the phones by pressing the reboot multiple key combination.
For more information, refer to
Multiple Key Combinations on page C-10 .
Since the APPLICATION APP_FILE_PATH attribute of the
address>.cfg files references the individual sip.ld files, it is possible to
verify that an update is applied to phones of a particular model.
For example, the reference to sip.ld is changed to 2345-11605-001.sip.ld to
boot the SoundPoint IP 601 image.
The phones can be rebooted remotely through the SIP signaling protocol.
Refer to Special Events on page A-16 .
The phones can be configured to periodically poll the boot server to check for
changed configuration files or application executable. If a change is detected,
the phone will reboot to download the change. Refer to Provisioning
on page A-90 .
Supporting SoundPoint IP 300 and 500 Phones
With enhancements in BootROM 4.0.0 and SIP 2.1.2, you can modify the
000000000000.cfg or .cfg configuration file to direct
phones to load the software image and configuration files based on the phone
model number. Refer to Master Configuration Files on page A-2 .
The SIP 2.2.0 or later software distributions contain only the new distribution
files for the new release. You must rename the sip.ld, sip.cfg, and phone1.cfg
from a previous 2.1.2 distribution that is compatible with SoundPoint IP 300
and 500 phones.
The following procedure must be used for upgrading to SIP 2.2.0 or later for
installations that have SoundPoint IP 300 and 500 phones deployed. It is also
recommended that this same approach be followed even if SoundPoint IP 300
and 500 phones are not part of the deployment as it will simplify management
of phone systems with future software releases.
Warning The configuration files listed in CONFIG_FILES attribute of the master configuration
file must be updated when the software is updated. Any new configuration files
must be added to the CONFIG_FILES attribute in the appropriate order.
Mandatory changes must be made or the software may not behave as expected.
